946.31(1)(1)Whoever under oath or affirmation orally makes a false material statement which the person does not believe to be true, in any matter, cause, action or proceeding, before any of the following, whether legally constituted or exercising powers as if legally constituted, is guilty of a Class H felony:

An arbitrator selected from a list provided by WERC is authorized by s. 111.10 to arbitrate as provided in ch. 298 [now ch. 788] and so is “authorized by statute" within meaning of sub. (1) (d). Layton School of Art & Design v. WERC, 82 Wis. 2d 324, 262 N.W.2d 218 (1978).

946.31 Annotation
Perjury consists of a false statement that the defendant knew was false, was made under oath in a proceeding before a judge, and was material to the proceeding. Materiality is determined by whether the trial court could have relied on the testimony in making a decision, not on whether it actually did. State v. Munz, 198 Wis. 2d 379, 541 N.W.2d 821 (Ct. App. 1995), 95-0635.

946.31 Annotation
A defendant may be charged with multiple counts of perjury based on testimony given in the same proceeding when each charge requires proof of an additional fact that the others do not. State v. Warren, 229 Wis. 2d 172, 599 N.W.2d 431 (Ct. App. 1999), 99-0129.

946.31 Annotation
Issue preclusion does not bar the prosecution of a defendant for perjury who was tried and acquitted on a single issue when newly discovered evidence suggests that the defendant falsely testified on the issue. The state must show that: 1) the evidence came to the state's attention after trial; 2) the state was not negligent in failing to discover the evidence; 3) the evidence is material to the issue; and 4) the evidence is not merely cumulative. State v. Canon, 2001 WI 11, 241 Wis. 2d 164, 622 N.W.2d 270, 98-3519.

946.32(1)(1)Whoever does either of the following is guilty of a Class H felony:

946.32(1)(a)(a) Under oath or affirmation or upon signing a statement pursuant to s. 887.015 makes or subscribes a false statement which he or she does not believe is true, when such oath, affirmation, or statement is authorized or required by law or is required by any public officer or governmental agency as a prerequisite to such officer or agency taking some official action.

946.32(1)(b)(b) Makes or subscribes 2 inconsistent statements under oath or affirmation or upon signing a statement pursuant to s. 887.015 in regard to any matter respecting which an oath, affirmation, or statement is, in each case, authorized or required by law or required by any public officer or governmental agency as a prerequisite to such officer or agency taking some official action, under circumstances which demonstrate that the witness or subscriber knew at least one of the statements to be false when made. The period of limitations within which prosecution may be commenced runs from the time of the first statement.

946.32(2)(2)Whoever under oath or affirmation or upon signing a statement pursuant to s. 887.015 makes or subscribes a false statement which the person does not believe is true is guilty of a Class A misdemeanor.

946.32 Annotation
This section applies to oral statements. The mere fact that a statement is permitted by law does not mean it is “authorized by law" within meaning of sub. (1) (a). State v. Devitt, 82 Wis. 2d 262, 262 N.W.2d 73 (1978).

946.32 Annotation
The reference to the statute of limitations in sub. (1) (b) does not make it an element of the offense. The statute of limitations is an affirmative defense and is subject to tolling under s. 939.74. State v. Slaughter, 200 Wis. 2d 190, 546 N.W.2d 490 (Ct. App. 1996), 95-0141.

946.32 Annotation
What is to be “authorized or required" under sub. (1) (b) is the oath itself, not the matter respecting which the oath is taken. State v. Slaughter, 200 Wis. 2d 190, 546 N.W.2d 490 (Ct. App. 1996), 95-0141.

946.41 Annotation
There is no exculpatory denial exception under this section. The statute criminalizes all false statements knowingly made and with intent to mislead the police. The state should have sound reasons for believing that a defendant knowingly made false statements with intent to mislead the police and not out of a good-faith attempt to defend against accusations of a crime. The latter can never include the former. State v. Reed, 2005 WI 53, 280 Wis. 2d 68, 695 N.W.2d 315, 03-1781.

946.41 Annotation

This section delineates one crime: a suspect's armed, physical refusal to be taken into custody. It can be committed by action or threat, which are alternative ways of threatening an officer to avoid being taken into custody. A jury instruction requiring unanimity on which occurred is not required. State v. Koeppen, 2000 WI App 121, 237 Wis. 2d 418, 614 N.W.2d 530, 99-0418.
